I saw a young band once who were ok. Nothing special. Singer was ok, again not the best ever voice but boy could he put on a show. He was a great frontman.
We had a rhythm guitar player who used to stand with the most miserable face staring at what he was playing. I despaired at him and gave up telling him to try to look interested. You are there not just to play music but to entertain. This boy made you look at the band and be interested.
